Cladding wood


Especially with old plank flooring joints are often present between the planks. If you want to close the slots, you can work with narrower joint widths with a finished sealant or your own filler. For wider joints, the effort to use wooden strips worthwhile, with each filling must be elastic.

Elasticity required

Unlike stone and ceramic tiles, the wood of planks, even when very old, must be considered a living material. Usual grout such as silicone or acrylic are not suitable for a wooden floor to fill joints.

Basically, there are two ways to fill the joints of planks. Special finished products and glue-wood flour mixtures as fillable filler are possible, but have a limited shelf life of up to ten years. The most durable, but also technically elaborate, type of jointing is the insertion of wooden strips that have to be individually adapted to each joint.
